Answer:
look at the picture i sent.......
The estimate for the number of people in the town who have not been to their doctor in the last year is 7062.
<h3>What are population and sample?</h3>
It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
Total population = 1819 + 6150 + 2003 + 5918 = 15890
Emily takes a random sample of 90 people from the town.
40 of these people have not been to their doctor in the last year.
The estimate for the number of people in the town who have not been to their doctor in the last year:
= (40/90)×15890
= 7062.22 ≈ 7062
Thus, the estimate for the number of people in the town who have not been to their doctor in the last year is 7062.

Answer:
Step-by-step explanation:
f(x)=4x+1
g(x) = x^2-5
(f*g)(x) = 4x^3+x^2-20x-5
Answer:
Discounted price = $495 Discount Rate = 34% Solution: Let x = Original Price x = 495 + 0.35x ;Multiply whole equation by 100 to remove decimals. 100x = 49500 + 35x ;Transpose 35x to the left side of the equation. 100x-35x = 49500 ; Subtract the x terms. 65x = 49500 ; Divide both sides by 65. x = 761.54 So the original price is $761.54.
This problem requires the use of the chain rule: dy / dt = [dy / dx] * [dx / dt]
y = √x => dy / dx = 1 / (2√x)
<span>(a) Find dy/dt, given x = 16 and dx/dt = 7.
dy/dt = [ 1/(2√x) ] * 7 = [1/(2*4)] * 7 = 7/8
(b) Find dx/dt, given x = 64 and dy/dt = 8.
dx/dt = [dy/dt] / [dy/dx] = 8 / [1/(2√64) ] = 128
